g l i w 5 g QAJ/ n m u Patented Oct. 29, 1929 PATENT OFFICE RODNEY V. NORTHEY, F TORONTO, ONTARIO, CANADA TOOL FOR REMOVING WEDGE KEYS FROM KEY BOLTS Application filed April 7,

In railway practice it is known to'use what are known as keybolts for securing the ends of the rails and angle bars together, with which bolts are used wedge keys which are driven through the slot of the bolt in a direction parallel to the side of the angle bar. After these wedge keys are driven home they are sometimes bent to prevent their accidental working loose. These wedge keys, on account of theirposition of use, and especially when bent, are very difficult to remove, and the object of my invention therefore is to devise a tool by means of which the withdrawal of the wedge keys may be facilitated.

I attain my object therefore by constructing a tool substantially as hereinafter described and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of part of an angle bar showin my tool in position for drivlng out the wedge key;

Fig. 2 an end elevation of the same; and

Fig. 3 a plan view of the same.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

1 is a rail and 2 the angle bar, which are provided with alined holes through which a keybolt 3 is passed, while through the slot l of the keybolt a wedge key 5 is passed to hold the parts together. As will be seen from the drawings, and particularly from Fig. 3, the straight side of the wedge key lies parallel to the side of the angle bar and partly underlies the head of theangle bar, and is inclined downwardly from the rear to the forward end and is therefore difiicult to get at wlth an ordinary hammer.

I therefore provide the special tool which I will now describe, and which comprises a segmento-spherical or ball-shaped metal body 6 provided with a socket in its top for receiving a handle 7. As will be seen from Fig. 2 of the drawings, the angle bar 2 is curved at the joint between its legs, and as the body 6 is ball-shaped, it will substantlall-y fit this curve, so that the angle bar may be used as a guide for the head of the tool.

The body 6 is provided at one side with an extension 8,1preferably slightly upwardly 1927. Serial No. 181,879.

inclined and which is provided with a recess 9 to receive the end of the wedge key. The opposite side of the body is provided with an extension 10 which is given an outward and upward inclination and provided with a curved striking surface 11. This extension 10 is provided with a striking face which, when the device is positioned against an angle bar, lies at less than a right angle to said bar. It will also be noted from Fig. 3 that a line drawn through the centre of the striking face and the axis of the handle intersects the end of the extension 8 close to the side adjacent the angle bar.

By inclining the handle to one side or the other, the tool may be rocked on the angle bar so that it may be easily engaged with the front end of the wedge key no matter how close the latter may be to the bottom leg of the angle bar.

The device is used by holding the tool by its handle with one hand and placing the tool at the angle between the legs of the angle bar and tilting the tool so that the end of the wedge key may be received in the recess.

Owing to the outward inclination of the extension 10, its striking surface is clear of the overhanging head of the angle bar, so that the striking surface may be struck by a hammer carried in the other hand of the workman. The upward inclination of the extension 10 is also of importance as the striking surface is then directed at the most natural angle to receive the blows from the hammer when the tool is being used.

From the above description it will be seen that I have devised a tool which will satisfactorily attain the object of my invention as set out in the preamble of this specification.
